I am in the process of building a new system, but am not able to get the monitor to turn on. Light remains yellow, if monitor is turned off then back on, received "No Signal" error. Any suggestions? Here is the system, now I will be the first to warn, to be honest I'm not sure if all components are compatible, so that could be the issue right there, but here they are: Asus A7N8X-E Deluxe AMD XP 2600 WD 120GB HD Radeon 9800 Pro Atlantis 1 GB DDR RAM CD Burner 16x DVD 400W Power supply (new) The only things plugged in are the drives, the mouse, keyboard, and monitor. Here is what is happening. I turn on system. CD and DVD drives are functioning (open/close and appear to "read" CD - at least think). System gives no beeps. Unable to determine if HD is functioning, but believe it is (new HD, nothing on it). Keyboard lights do no come on, including if I hit Caps lock or num lock. Some thoughts: Incompatible RAM? I did not research as much as I could have so not sure if this is possibility. If RAM is removed, the same thing happens. All slots have been tested. Dead CPU? As I have mentioned in other posts, I recently lost 2 HDs at the same time with burnt circuit boards on them. This CPU is from that system so not sure if it was damaged at the same time. I did attempt putting another CPU that I believe should be compatible with the board but it did not change results. Dead HD? Brand new, never been tested so do not know if this is possibly a culprit. I had thought possibly bad or incompatible video card, but I tried a second one and had same results (however, once again, this video card was from the "fried" system). One last thing, my friend that was helping put it together said there was a small plastic piece on the AGP slot that he removed. I do not know where he put it, not sure if it's important. Thanks for any help!

disconnect all cables from drives & remove all cards except video card from board & power up & post results david

Am I correct in assuming you mean no HD, DVD, or CD. Keep mouse, keyboard, and monitored plug in, as well as video card? For good measure I did the above, as well as once without the mouse and keyboard. All gave same result...same as before. I also forgot to mention, I did try plugging headphones into the back to see if the beeps may be coming through there...still no beeps. Thanks!

make certain cmos jumper in normal not clear position, possible to use old ps & old ram david

I'll assume that the system speaker is in fact connected. The absence of any beep codes says that you are not going very far into POST. This leaves three main possibilities. 1 CPU is dead (you've tried another) 2 Motherboard is DOA 3 PSU is not supplying correct voltages or is not supplying 'power good signal' Determining which one is the case requires some technical proficiency. One thing you could check, is the CPU fan spinning?

The jumper is in the normal position. I also went ahead and "reset" the BIOS in case that was the problem. Still same results. I'm very hesitant to use old PS due to the problem with my previous 2 HDs. I am concerned the problem may have been from PS and don't want to blow a whole new system. As far as RAM, unforunately the RAM I had was an older version (PC133, can't recall what "kind" it is). THe new stuff is PC3200. I may be able to get some RAM from someone else, but would have to find someone with the same kind and that is will to give it up for a test. Thanks again! One other question...could it be an improperly grounded MB?

take board out of case, isolate from case with esd bag??? so you can still use ps. you don't have to have same speed ram, cam be slower or faster. old ram is dimm, new ram is ddr. david
